Relationship to exercise may indicate runner’s hematuria Pain? Association with flank pain suggests infection, calculus, or obstruction Painless bleeding is associated with cancer or glomerulonephritis Association with hesitancy, frequency, or decreased force of stream is suggestive of prostatic hypertrophy Constipated? Straining can cause minor prostatic bleeding Currently in menses? Review all medications for any which might cause hematuria, such as aspirin, NSAIDs, some antibiotics (Cipro, Bactrim, PCN, cephalosporins), omeprazole, furosemide Determine type of hematuria: Initial Hematuria Arises from a lesion within the penile or bulbous portions of the urethra Causes may include: cancer infection trauma excessive masturbation foreign body such as a calculi Total Hematuria Present throughout the entire voiding, must have a source higher than the bladder neck in order for the blood to thoroughly mix with the urine prior to the onset of voiding. Such conditions may be: bladder, ureters, or kidney cancer infection, inflammation trauma of the bladder, kidney, or ureters P age |2 TB of the bladder or kidney, stones in the bladder or kidney. Terminal Hematuria Exists when the urinary stream is visibly clear until the end of voiding, at which time the last part of the urine becomes grossly bloody, or when blood is passed from the meatus after the patient thinks that urination has ceased. This is usually from: BPH prostatitis, bladder cancer (rarely) Source: Gleich, P. (May 2004) Hematuria: Is it from UTI or something more serious? Consultant, pp. 749-754. Gross hematuria usually indicates a serious problem; fairly high correlation with malignancy (typically a transitional cell carcinoma) Microscopically detectable blood is less likely to signal a major underlying condition; a finding of 0-3 RBCs/HPF is probably innocent Workup for gross and microscopic hematuria focuses on disturbances of urinary tract function and includes H&P, urinalysis, radiologic imaging, urine cytology, and cystoscopy. Presence of hematuria, proteinuria, and renal insufficiency warrants referral to a nephrologist. Most common causes of hematuria: For men: < age 40: STDs > age 40: bladder cancer, BPH For women: bacterial cystitis < age 40: UTI age 40-60: bladder tumors, UTI, calculi > age 60: bladder tumors, UTI [Consider child abuse in children] False-positive results from foods such as beets and blackberries, vaginal bleeding, myoglobin (exercise), drugs, and factitious sources.

Microscopic hematuria. N Engl J Med 348(23), 2330-2338. When asymptomatic microscopic hematuria is detected, the UA should be repeated a few days later before any workup is initiated, especially if the patient has had vigorous exercise, menstruation trauma to the urinary tract, or sexual activity just before the collection. If microscopic hematuria is absent on repeated testing, no further evaluation is recommended unless the patient has risk factors for bladder cancer or transitional-cell cancer of the urinary tract, such as cigarette smoking or exposure to toxins. If repeat testing shows continued microscopic hematuria, a glomerular source should be considered, especially with the presence of red-cell casts. o Primary care should follow-up at 6 months and then annually, to check for the development of proteinuria or renal insufficiency. o If microscopic hematuria is accompanied by proteinuria or renal insufficiency, the patient should be referred to a nephrologist for evaluation. Diagnostic Tests: microscopic urinalysis screening lab tests as appropriate (may need ANA, ASO antibody, RPR, CBC, PPD, urine for acid-fast bacilli, PSA) urine cytology Bladder tumor antigen FISH test Abdominal x-ray (KUB to check for stones) IVP Renal/bladder ultrasound (to check for obstruction, anatomical defects) CT (without radiographic contrast medium if stone disease suspected clinically; perform without and then with contrast for detection of stone disease or a mass (in the upper urinary tract or possibly in the bladder) Refer for Cystoscopy (to check for bladder irritation, transitional cell carcinoma [TCC]) Follow-up In 20% of patients, despite a thorough workup, the cause is still unknown. Studies of 5-year follow-up of patients who have undergone a previously negative workup have shown that the future incidence of serious disease is low. Summary “Urine should not contain any blood.” Gross hematuria usually indicates a serious problem; its correlation with malignancy—typically a transitional cell carcinoma—is fairly high. Microscopically detected blood is less likely to signal a major underlying condition. Presence of hematuria, proteinuria, and renal insufficiency warrants referral to a nephrologist. If hematuria persists, repeat the urinalysis and cytology every 6 months until the problem resolves or 3 years have passed. P age |6 Acute Urinary Tract Infection Etiology: Largely a disease of sexually active females Female to male incidence ratio of UTI is 2:1 after age 60 UTIs are the most common bacterial infection in the elderly and are a common source for bacteremia Gram-negative coliforms are responsible for the majority of bacterial infections, with Escherichia coli predominating. Symptoms: Lower Urinary Tract: Dysuria Frequency Nocturia Suprapubic pain Hematuria Malodorous urine Incontinence Upper Urinary Tract: flank pain fever nausea and vomiting mental changes (in the elderly) NOTE: Atypical presentations such as falls, change in mentation, loss of appetite, nocturia, difficulty urinating, and new incontinence are common symptoms of UTI in elderly patients. Clinical findings (Key signs): Lower UTI: suprapubic tenderness Upper UTI: flank tenderness fever tachypnea tachycardia mental status changes (in the elderly) vomiting Diagnostic Tests: Urine dip (screening test) P age |7 biochemical screening tests include nitrite reduction and leukocyte esterase tests These screening methods are insensitive at bacterial counts < 100,000 colony-forming units/ml. Microscopic examination & culture of clean midstream urine pyuria: 10 or more WBC/ml In absence of a (+) culture (< 100 uropathogens/ml), pyuria suggests infection by chlamydia or Neisseria gonorrhoeae, or tuberculosis WBC casts noted on microscopy strongly suggest pyelonephritis (upper UTI) in patients with UTI symptoms Blood culture (in toxic or elderly patients with signs of upper UTI) Differential Diagnosis: Acute bacterial lower UTIs in females may be mimicked by urethritis caused by C. trachomatis, N. gonorrhoeae, and herpes simplex virus. Vaginitis from Candida albicans and Trichomonas vaginalis or bacterial vaginosis also may cause dysuria. Acute upper UTI can be mimicked by diverticulitis, appendicitis, pneumonia, intestinal obstruction, and nephrolithiasis. Making the Diagnosis: Source: Schulz, L, Hoffman, RJ, Pothof, J, & Fox, B. (2016) Top ten myths regarding the diagnosis and treatment of urinary tract infections. J. Emerg Med, 51(1), 25-30 Check out the myths at http://www.medscape.com/viewarticle/865175_print ….how many have you believed in the past? Bottom line: Asymptomatic bacteriuria is overtreated. “Diagnosis should be based on clinical symptoms whenever possible, and confirmed by positive urine microscopy and culture.” Treatment: Acute bacterial uncomplicated lower UTIs in females 3-5 days of oral outpatient therapy with TMP-SMX (if PCN or cephalosporin is used, must give for 7 days) Fluoroquinolones: ciprofloxacin and levofloxacin Nitrofurantoin (5-7 days) Uncomplicated bacterial upper UTIs in females and males: 14 days of oral or parenteral antibiotics; may need hospitalization (hospitalize if pregnant) Uncomplicated bacterial lower UTI in males: 14 days Source: Keys, TF (July 2000). 1-Minute Consult: When should asymptomatic bacteriuria in the elderly be treated? Cleveland Clinic Journal of Medicine, 67(7), 466-467. Urinary incontinence, cystoceles, and lack of estrogen are risk factors that predispose elderly women to bacteriuria. In men, obstructive uropathy is the usual culprit. P age |8 Elderly patients with asymptomatic bacteriuria are not at risk for developing a UTI or renal damage. Treatment is necessary only when the patient has a symptomatic UTI or is at risk for developing a more significant complication, such as if the patient has diabetes or is immunocompromised. Recurrent infections that cannot be eradicated can sometimes be suppressed by antibiotics. This should be avoided, however, unless the patient is symptomatic or developing complications, because it can often lead to infection with resistant organisms. Factors that would designate a UTI as complicated include: Age > 65 years Indwelling catheter Recent GU instrumentation Urinary calculi Renal impairment Prostatic involvement DM Renal transplant Neutropenia Recent antibiotic therapy Recurrent UTI Pregnancy (cannot use quinolones during pregnancy or sulfonamides near delivery date; cephalexin is a reasonable 1st choice) Steroid therapy Immunocompromising disease Known structural or functional impairment Patient Education Stay well hydrated In female patient: voiding after intercourse for prophylaxis Alternate contraception if recurrent UTI is associated with use of diaphragm Consider chemoprophylaxis with recurrent lower UTI Follow-up: UTI in men and complicated UTI require initial culture, and repeat culture after completion of therapy Thorough GU examination needed with: UTI in men Recurrent and complicated UTIs in females P age |9 Interstitial Cystitis (IC) Definition/Cause A chronic inflammatory condition of the bladder. Its cause is unknown. Unlike common cystitis, which is caused by bacteria and usually successfully treated with antibiotics, IC is believe not to be caused by bacteria and does not respond to conventional ABT therapy. It is not a psychosomatic disorder nor is it caused by stress. It is not associated with bladder cancer. Impact of Delayed Bladder Pain Syndrome/Interstitial Cystitis Diagnosis (Source: Evans, RJ, & Stanford, EJ. (2006). J. Reprod Med. 51(3 suppl), 241-252.) From the initial development of symptoms until the diagnosis 5-7 years later, patients: See at least 5 providers before the diagnosis Experience significant suffering and reduced quality of life May have unnecessary surgical procedures Symptoms Frequency o Day and/or night frequency of urination (up to 60 times/day in severe cases) o In early or very mild cases, frequency is sometimes the only symptom Urgency o May also be accompanied by pain, pressure or spasms Pain o Can be in the lower abdominal, urethra, or vaginal area o Pain also frequently associated with sexual intercourse (dyspareunia) o Men with IC may experience testicular, scrotal and/or perineal pain, and painful ejaculation Other disorders o Muscle and joint pain o Migraines o Allergic reactions o GI problems o IC sometimes associated with certain other chronic diseases and pain syndromes such as vulvodynia, vulvar vestibulitis, fibromyalgia, chronic fatigue syndrome and IBS Triggers: diet, sexual activity, allergens Diagnosis Urine culture to rule out bacterial infection Rule out other diseases and/or conditions that have symptoms resembling IC o Bladder cancer o Kidney problems o Tuberculosis o Vaginal infections o STDs o Endometriosis o Radiation cystitis o Neurological disorders P a g e | 10 Cystoscopy with hydrodistention under general anesthesia o Done if no infection present and no other disorder is discovered o If distention under anesthesia is not performed, diagnosis of IC may be missed o Cystoscopy during a routine office visit may not reveal the characteristic abnormalities of IC and can be painful for those who have IC o Necessary to distend the bladder under general or regional anesthesia in order to see the pinpoint hemorrhages on the bladder wall that are the hallmark of this disease o A biopsy of the bladder wall may be necessary at this time to rule out other diseases such as bladder cancer and to assist in the diagnosis of IC Treatment Oral medications o Elmiron (pentosan polysulfate sodium) FDA approval in 1996 Only oral medication approved specifically for use in IC Believed to work by repairing a thin or damaged bladder lining o Antidepressants Tricyclic antidepressants such as Elavil (amitriptyline) Help with both the pain and frequency of IC Used for their anti-pain properties, not as a treatment for depression o Other oral meds Anti-inflammatory agents Antispasmodics Bladder analgesics (such as Urimax) Antihistamines Muscle relaxants Bladder installations o Bladder distention with water under general anesthesia (diagnostic and may be therapeutic as well) o DMSO (dimethyl sulfoxide) as anti-inflammatory o BCG (bacillus Calmette-Guerin) experimental; to boost immune system o Cystistat (hyaluronic acid) in clinical trial; replace defective lining of bladder Other treatments o Diet Eliminating acidic, spicy foods may decrease severity of IC Smoking, drinking coffee or tea, and alcoholic beverages may aggravate IC o Self-help Stress reduction, visualization, biofeedback, bladder retraining and exercise o Electronic nerve stimulators o Surgery (only if severe symptoms); cystectomy, urinary diversion P a g e | 11 Bladder Cancer Source: Sharma, S, Ksheersagar, P, & Sharm, P.

(May 20, 2015). First study on bladder cancers presenting as UTIs. Accessed via Medscape at http://www.medscape.com/viewarticle/845081_print Clinical pearl: Persistent symptoms characteristic of UTI that do not improve with time or treatment may be due to bladder cancer. Because bladder cancer most commonly presents as hematuria, UTI-like symptoms do not always raise suspicion for bladder cancer Women have a longer interval from UTI to diagnosis of bladder cancer than men. Overactive Bladder/Urinary Incontinence Source: Rosenberg, MT, & Dmochowski, RR (February 2005). Overactive bladder: Evaluation and management in primary care. Cleveland Clinic Journal of Medicine, 72(2), 149-156. Definition, Prevalence, & Significance: Overactive bladder is defined by the International Continence Society as a feeling of urinary urgency at least 4 times in the past month, with or without urge incontinence, usually with urinary frequency (more than 8 micturitions per day) and nocturia, but without pathologic or metabolic factors that would explain the symptoms. Urinary incontinence (UI) is defined as “involuntary loss of urine sufficient to be a problem” Because it is frequent and embarrassing, UI is often accepted, underreported and undertreated (about 50% of individuals with UI have not reported their symptoms to an MD or NP). Only 15% of people with overactive bladder seek treatment. Incidence and prevalence increase with age and are related to cognitive and functional impairments Affects approximately 15-30% of noninstitutionalized older persons (19% of men, 39% of women) In nursing facilities between 50-70% of the 1.5 million residents are incontinent of urine (30% of this group also experience fecal incontinence) due to functional dependency Social and psychological impacts of UI: Significant changes in social activities outside of the home Depression Social isolation Anxiety about potential disclosure to friends that UI is a problem Embarrassment about accidents in public Enforced changes in sexual activity What is needed to maintain continence? Integrity of the bladder and urethra Intact neurological system that provides voluntary and coordinated control of voiding Pattern of urine production Desire and physical capability of the person to perform the activities associated with normal toileting Spinal reflex contraction impulses are continually generated between the spinal column and the bladder. Continuous inhibitory signals from the brain (in the pons) normally prevent these contraction signals from causing bladder contractions. In older persons suffering progressive brain failure or other cerebral change, the loss of these inhibitory signals can, when combined with other predisposing factors, result in enough of a bladder contraction to provoke leakage. P a g e | 13 Some apparent “stress incontinence,” in which the individual experiences urine leakage after coughing or some other sharp increase in intraabdominal pressure, is in fact caused by uninhibited bladder contractions. ** An important factor in women is loss of the vesicourethral angle (the angle at the juncture of the bladder and the urethra) as a result of overstretching of pelvic muscles during childbirth and relaxation of pelvic muscles after menopause related to estrogen deficiency. Predisposing and Age-Related Factors in Urinary Incontinence: Increased residual urine Diminished bladder capacity Decreased bladder sensitivity Detrusor instability Prostatic hypertrophy Increased nocturnal urinary output Prior childbirth Obesity Smoking Estrogen withdrawal and menopause Brain failure Dysmobility Factors Precipitating Urinary Incontinence: Relocation Inappropriate environment UTI Other acute illness Intravesical lesions Medications Urinary obstruction Neurological lesions Atonic bladder (as with diabetic autonomic neuropathy) Reflex neurogenic bladder Uninhibited neurogenic bladder Detrusor-sphincter dyssynergia Common Causes of Transient (Acute) Incontinence (fairly sudden or recent onset of symptoms): Delirium or confusional state Symptomatic urinary infection Atrophic urethritis or vaginitis Drugs Sedatives or hypnotics, especially long-acting agents Loop diuretics Anticholinergic agents Alpha agonists/antagonist P a g e | 14 Calcium channel blockers Psychological problems, including depression Endocrine disorders (hypercalcemia, hyperglycemia) Restricted mobility Stool impaction or constipation (especially causes urge incontinence due to stool pressing on bladder) Types of Persistent Urinary Incontinence: Stress incontinence Leakage with physical activity or increased intraabdominal pressure (as with chronic obstructive pulmonary disease and obesity) Small to moderate volume leaks Usually in daytime only; infrequently nocturnal Due to sphincter incompetence; urethral instability Causes: pelvic prolapse in women, sphincter weakness or damage (such as following prostatectomy, medications such as alpha-adrenergic antagonists) Urge incontinence Leakage following a strong uncontrollable urge to void or inability to delay voiding Moderate to large volume – a “gush” Urinary frequency, nocturia, possible suprapubic discomfort Due to detrusor overactivity (instability or hyperreflexia) Causes: CNS damage (stroke, Alzheimer’s, brain tumor, Parkinson’s disease), interference with spinal inhibitory pathways, local bladder disorder, insulin-dependent diabetes mellitus, depression, and medications including diuretics, caffeine, sedative-hypnotics, and alcohol Overflow incontinence Leakage without the urge to void, from a distended or obstructed bladder; intermittent or continuous Volume varies Hesitancy, straining to void, weak or interrupted urine stream; occurs day or night Due to outlet obstruction or underactive detrusor Causes: Obstruction (BPH, bladder neck obstruction, urethral stricture), underactive detrusor (as with herniated disk, spinal cord injury, diabetic neuropathy), anticholinergic/antispasmodic drugs Functional incontinence Factors outside the urinary tract cause the loss of urine: mobility problems, cognitive deficit, sedatives, environmental barriers, etc. History: Source: Diamond, S. (Jan 1, 2005). The 15-minute visit: Female urinary incontinence. Accessed at http://www.patientcareonline.com In addition to HPI, the past medical history (checking for points mentioned above) is very important OB/GYN history: number and timing of pregnancies, method of delivery, history of pelvic surgeries (all of which may weaken abdominal musculature) P a g e | 15 Bowel and bladder history; 24-hour micturition diary (frequency of leakage, time of food drink, and activities) Functional limitations, as with elderly patient with arthritic joints, may prevent the patient from having enough time to manage all of the necessary steps of toileting Physical Exam: Abdominal exam: check for increased abdominal fluid or organomegaly Pelvic exam: check for cystocele, atrophic vaginitis, infection; ask patient to cough and check for urine loss Neurological: Deep tendon reflexes to evaluate lumbosacral plexus Diagnostic Tests: U/A Postvoid residual measurement Three measurements between 50 and 200 ml is normal, but consistently above 100 ml should be closely monitored Simple cystometry to evaluate bladder filling, storage, and emptying Abnormal findings include first desire to void at < 100 ml, pain or incontinence during filling, a bladder capacity of < 400 or > 650 ml Uroflowmetry (listen while the patient voids) Should be smooth, uninterrupted, and initially strong Urodynamic studies (reserved for those unresponsive to a trial of treatment for the type of UI diagnosed or where surgery is anticipated) Treatment for Urinary Incontinence: Primary methods of treatment are behavioral, not pharmacologic. Behavioral Treatment (educating the patient about UI to change the individual’s response to UI symptoms) Maintain a bladder schedule (fixed interval, e.g., every 2-3 hours -- voiding too often or too little can cause deconditioning of the bladder) Bladder training (progressively longer intervals) Promote fluid intake (many patients deliberately restrict their intake to reduce “accidents.”) – concentrated urine can produce debris or in itself can be a bladder irritant. ½ the body weight in pounds is the number of ounces of liquid needed per day Avoid bladder irritants such as caffeine, tomatoes, citrus fruits, Equal Promote bowel regularity (constipation makes bladder symptoms worse) Practice urge control (urges are not a command to void, just a reminder that the bladder is filling) Do pelvic muscle exercise (30-80/day) Kegel exercises can decrease incontinency number (stress, urge) by ½ (whether “wet” type due to leaking or “dry” type due to whether can make it to the bathroom in time) Electrical simulation treatment (with implants) “Double voiding” can reduce residual volume, decreasing the reservoir for infection and the constant presence of urine available for leakage Most elderly men should sit down to urinate; it is safer, and it ensures the bladder is more fully emptied each time. Pelvic floor dysfunction physical therapy P a g e | 16 Pharmacological Treatment For bladder wall: First line: anticholinergics Most commonly used: oxybutynin [Ditropan, Ditropan XL], tolterodine [Detrol, Detrol LA] Others used: trospium chloride (Sanctura), solifenacin (Vesicare), darifenacin (Enablex) and oxybutynin patch (Oxytrol) Most recently approved: fesoterodine (Toviaz) NOTE: oxybutynin and tolterodine can precipitate anticholinergic psychosis Beta3-receptor agonists: mirabegron (Myrbetriq) (approved in 2012) Tricyclics (imipramine, doxepin) Can cause cardiac dysrhythmias and mental status changes; use with caution in elderly patients Detrusor injections of botulinum toxins (for adults with OAB who cannot use, or do not adequately respond to, anticholinergic medication) For urethra: alpha-adrenergics (pseudoephedrine), estrogen, alpha-blockers (Minipress, Hytrin), central relaxants (baclofen [Lioresal], dantrolene [Dantrium], diazepam [Valium]) Surgical Artificial urinary sphincters Prostatectomy or TURP Dilation of urethral stricture Circumcision Penile reconstruction Urinary diversion Suprapubic catheter Equipment and Devices Absorbent products Skin care Devices and urinals External catheters Indwelling urethral catheters Intermittent catheterization Complications (From: Rosenberg & Dmochowski, page 150) Physical comorbidities and consequences of incontinence, such as skin ulceration, UTI, increased incidence of falls and fall-related fractures, and sleep disturbances Psychological and lifestyle-related consequences include restricted mobility, impaired work productivity, social isolation, impaired sexual functioning, and depression, with a significant reduction in health-related quality of life. P a g e | 17 Pyelonephritis Definition: Acute pyelonephritis (APN) is an acute infection of the upper urinary tract (collection system and renal parenchyma) Usually occurs when colonic bacteria ascend through the urinary tract to invade the renal parenchyma More common in females due to short length and position of urethra E. Coli most common cause (others include Proteus, Klebsiella, Staphylcoccus saprophyticus, and Enterococcus Key Symptoms: Fever (101-105 degrees) Chills Dysuria, frequency, or urgency Back or flank pain Nausea or vomiting Key Signs: Fever CVA tenderness (Note: Cystitis: no fever, no CVA tenderness) Conditions that can be confused with APN include: PID Acute appendicitis Acute cholecystitis nephrolithiasis Urinalysis: (+) leukocytes, (+) nitrite, may have WBC casts Treatment: Factors favoring hospitalization include: Geriatric age group Underlying medical condition such as DM or pregnancy Male gender (higher frequency of anatomic abnormality) Known GU tract abnormality Uncontrolled N & V Signs of possible sepsis (hypotension, altered mentation) Pregnancy Poor social support Unable to comply with treatment Consider outpatient management for otherwise healthy young females who are reliable and who are tolerating oral intake. P a g e | 18 Drug of choice (for outpatients): fluoroquinolones, trimethoprim-sulfamethoxazole, amoxicillinclavulanate Treat 10 days (in less ill patients) to 14 days (in more ill or pregnant patients). Follow-Up: Brief visit (or at least phone follow-up) after 1-2 days to document clinical improvement Failure to improve or worsening symptoms after 48-72 hours of outpatient treatment may represent obstruction or abscess (will need ultrasound or IVP). A “test of cure” urine culture should be obtained approximately 2 weeks after the completion of antibiotic therapy. Glomerulonephritis (GN) Etiology: either idiopathic (due to primary kidney disease) or secondary (associated with a systemic disease such as lupus or infectious such as poststreptococcal GN (80% of these cases occur in children) Key Symptoms: SOB, leg or facial edema Dark urine (“Coke-colored”) Symptoms suggesting secondary GN: Pharyngitis or skin infection 2-3 weeks earlier (suggests poststreptococcal GN) Joint pain (suggests lupus nephritis, cryoglobulinemia, or polyarteritis nodosa) Hemoptysis (suggests Wegener’s granulomatosis, Goodpasture’s syndrome) Sinusitis (suggests Wegener’s granulomatosis) Fever (suggests endocarditis, lupus nephritis) Heart murmur (suggests endocarditis) Diagnostic Tests: Dipstick (proteinuria +/-) U/A (asymptomatic hematuria, especially RBC casts) BUN, creatinine (GN frequently causes renal failure) CBC (anemia seen in many cases of GN; thrombocytopenia suggests lupus nephritis) 24-hour urine for creatinine clearance and protein (protein excretion is usually < 3 gm, but a minority of patients may be nephrotic) Blood cultures (to screen for endocarditis) Antistreptolysin O (ASO) titer, streptozyme titer (if elevated, suggests poststreptococcal GN) Serum antinuclear antibody (ANA) (positive at high titer in lupus nephritis) Serum complement (C3, C4, CH50) (low in poststreptococcal GN, endocarditis-associated GN, lupus nephritis) Kidney biopsy (helps to define the etiology) Treatment: No specific medical therapy indicated for poststreptococcal GN Appropriate antibiotic therapy required in endocarditis P a g e | 19 Prolonged treatment with corticosteroids and cyclophosphamide for lupus nephritis Diuretics often needed to treat volume overload and hypertension Dialysis may be required in patients with GN accompanied by severe renal failure Diet: Dietary sodium restriction (2 gm/day) to prevent volume overload and hypertension If patient is hyperkalemic, potassium restriction is also indicated Follow-Up: Long-term follow-up as outpatients for adjustment of medications to produce and maintain a clinical remission and monitor for med side effects Labs: U/A, BUN, creatinine, lytes, serum complement Nephrotic Syndrome From: Kodner, C. (November 15, 2009) Nephrotic syndrome in adults: Diagnosis and management. American Family Physician, 80(10), 1129-1134. In nephrotic syndrome, a variety of disorders cause proteinuria, often resulting in marked edema and hypoalbuminemia. Most cases of nephrotic syndrome appear to be caused by primary (idiopathic) renal disease (focal segmental glomerulosclerosis, membranous nephropathy, IgA nephropathy Common secondary causes of nephrotic syndrome include diabetes mellitus (most common), SLE, hepatitis B or C, use of NSAIDs, amyloidosis, multiple myeloma, HIV, and preeclampsia. Presenting symptoms: progressive lower extremity edema, weight gain, fatigue In advanced disease: periorbital or genital edema, ascites, pleural or pericardial effusion o ** Persons who present with new edema or ascites, without typical dyspnea of heart failure or risk factors of cirrhosis, should be assessed for nephrotic syndrome. Lab findings o Urine dipstick proteinuria of 3+ o Random urine protein/creatinine ratio of 3-3.5 represents nephrotic-range proteinuria o Low serum albumin (< 2.5 g/dL) o Severe hyperlipidemia (cholesterol > 300-400 Complications o Venous thromboembolism due to loss of clotting factors in the urine o Infection due to urinary loss of immunoglobulins o Acute renal failure Management o Limit sodium intake to 3 g/day o May need to restrict fluid intake to < 1.5 L/day o Diuretics (target weight loss of 1-2 lb/day to avoid acute renal failure or electrolyte disorders) Loop diuretics such as furosemide or bumetanide given IV o ACE Inhibitor to reduce proteinuria and reduce risk of progression to renal disease o Unknown benefit: albumin IV, corticosteroids, lipid-lowering treatment.

Treatment and prevention of kidney stones: An update. American Family Physician, 84(11), 1234-1242. Lifetime prevalence of 10% in men, and 5% in women Prevalence increasing in the US Presentation: moderate to severe colic caused by the stone entering the ureter (stones in the renal pelvis may be asymptomatic); often accompanied by hematuria, nausea or vomiting, and malaise. Fever and chills may also be present o Stones in proximal (upper) ureter cause pain in the flank or anterior upper abdomen o Stones in the distal third of the ureter cause pain in the ipsilateral testicle or labia o Stones at the junction of the ureter and the bladder often cause dysuria, urgency, and frequency and may be misdiagnosed as a lower urinary tract infection Absence of hematuria does not exclude urolithiasis Differential diagnosis: MSK pain, herpes zoster, diverticulitis, duodenal ulcer, cholecystitis, pyelonephritis, renal infarction, renal hemorrhage, gynecologic disorders, ureteral obstruction Renal infarction (From: Burg, MD, & Groenewoud, HW (November 2004). Kidney stone or renal infarction? Emergency Medicine, 47-51.) o o Some patients with renal infarctions may not have flank pain (probably underdiagnosed) Cardiac disease of various types predisposes patients to emboli that are the major cause of renal infarctions o A CT scan will almost always definitively diagnose a renal infarction ** If renal infarction is being pursued via CT, IV contrast must be given, although it is not needed to visualize kidney stones o Severe hypertension may occur If entire kidney has been infarcted, a total nephrectomy is commonly performed to relieve the extreme renovascular hypertension Evaluating acute renal colic: obtain CBC, UA, chemistry, CT scan Management of acute stone events o Most are smaller than 5 mm and will pass without interventions o Larger stones (but less than 1 cm) may require lithotripsy o Stones larger than 1 cm may require lithotripsy or ureteroscopy o Pain management: parenteral NSAIDs often as effective as narcotics o Antispasmodies to facilitate stone passage Alpha blockers (doxazosin, tamsulosin) Calcium channel blockers (nifedipine [Procardia, sustained release]) P a g e | 21 o Induce high urine flow with oral intake of at least 2-3 L of fluids/24 hours to ensure a urine output of at least 2 L/day o Stone analysis should always be done whenever stone material is available (Strain the urine!) Prevention of recurrent stones o Stones recur in 30-50% of patients within 5 years o Increase daily fluid intake o For prevention of calcium phosphate and struvite stone, acidify urine (lower than 7) Cranberry juice: at least 16 oz/day Betaine: 650 mg orally 3 times/day with meals o For prevention of calcium oxalate, cysteine, and uric acid stones, urine should be alkalinized Potassium citrate 10-20 mEq orally with meals Calcium citrate: two 500 mg tablets/day with meals o If found to have hypercalciuria, treat with high fluid intake, dietary sodium restriction, and thiazide diuretics (calcium restriction is not advised) Consider primary hyperparathyroidism: Check intact parathyroid hormone level Renal Cell Carcinoma (RCC) Source: Curti, BD (July 7, 2004).

On testing for proteinuria: Time for a methodical approach. Cleveland Clinic Journal of Medicine (70)6, 493-501. “Proteinuria is often transient and benign, but persistent proteinuria can be a manifestation of a systemic disease.” (Kashif, p. 535) P a g e | 22 Summary of evidence (Eknoyan, p. 493): Even relatively small increases in protein or albumin in the urine are an early sign of kidney injury and often precede any detectable change in the serum creatinine concentration or glomerular filtration rate. Protein in the urine is more than a marker: persistently high levels damage the kidney and contribute to progressive loss of kidney function In persistent proteinuria, the amount of protein excreted bears a direct correlation to the rate of loss of kidney function Interventions that reduce the amount of protein in the urine in persistent proteinuria retard the progression of chronic kidney disease Proteinuria is a strong and independent predictor of increased risk for cardiovascular disease and death, especially in people with diabetes, hypertension or chronic kidney disease the elderly (may be surrogate marker for progressive atherosclerosis) The amount of protein excreted shows a strong and close correlation with the risk of death from cardiovascular disease at all levels of excretion Normal rate of protein excretion in healthy adults is < 150 mg/day o < 30 mg of this is albumin, which has a molecular weight just big enough to keep it from passing through the normal, intact glomerular membrane o The rest is composed of different proteins and glycoproteins from tubular epithelial cells (Eknoyan, p. 493) Mechanisms of proteinuria (Kashif, pp. 535-536) 1. Increased glomerular filtration of normal plasma proteins due to altered glomerular permeability (glomerular disease) 2. Inadequate tubular reabsorption of the small amounts of normally filtered proteins (tubulointerstitial diseases) 3. Overflow of elevated normal or abnormal plasma proteins (plasma cell dyscrasias) 4. Increased secretion of tissue proteins from the epithelial cells of the loop of Henle (TammHorsfall proteinuria) Approach to a patient with proteinuria (Kashif, p. 537) After a positive dipstick test (+ proteinuria), check for conditions that can cause false-positive results such as: o Highly alkaline urine (pH > 7) o Concentrated urine o Gross hematuria o Mucus, semen, or leukocytes o Iodinated contrast agent o Contamination with chlorhexidine or benzalkonium If false positive likely, repeat the dipstick after the condition resolves P a g e | 23 If false positive is NOT likely, check for conditions that alter renal hemodynamics such as exercise, febrile illness, congestive heart failure o If one of these conditions is present, reassure the patient for now and repeat the urine after the condition resolves (1-2 weeks) o If these conditions are absent, repeat the dipstick test If the proteinuria is not present (“nonpersistent proteinuria”), then just reassure the patient If the proteinuria IS present (“persistent proteinuria”), the order a 24-hour urine protein or spot urine protein-creatinine ratio 1. If non-nephrotic-range proteinuria (<3.5 g/day) or the proteincreatinine ratio is < 3.5, perform two sequential 12-hour urine collections to rule out postural proteinuria 1. If postural, reassure patient 2. If nonpostural OR if the 24 hour urine protein showed nephrotic-range proteinuria (>3.5 g/day) or the proteincreatinine ratio was >3.5, start workup for renal or systemic disease. If no system disease, presume primary renal and biopsy for confirmation.

Microalbuminuria: Is it a valid predictor of cardiovascular risk? Cleveland Clinic Journal of Medicine, 70(3), 255-261. Microalbuminuria is defined as albumin excretion of 30-300 mg/24 hours or an albumin-tocreatinine ration > than 30 mg/g in a first morning midstream sample. Predictor of cardiovascular events in high-risk populations Assess for microalbuminuria in: o Patients with diabetes type 2 o Older patients with diabetes type 1 o Older patients with hypertension ( ≥ 160/100 mm Hg) Remember, urine dipstick can only detect albumin at levels greater than 30 mg/dL (approximately 300 mg/24 hours). So (+) protein on a urine dipstick is actually macroalbuminuria.

If a hydrocele develops spontaneously between the ages of 18 and 35, careful evaluation should be made to exclude cancer. Treatment: If very tense, large – may require surgical repair. Otherwise, active therapy is not required. An athletic supporter may relieve symptoms. Epididymitis Two major forms: bacterial and sexually transmitted Sexually transmitted (usually < 35 years of age) Chlamydia, gonorrhoeae, ureaplasma, gram-negative rods Bacterial (seen with anatomic abnormalities) P a g e | 26 Usually > 35 year after prostatectomy, prostatitis, BPH E. coli, Pseudomonas Can also occur in children from pathologic connection from the GI or urinary tract to the genital duct system Amiodarone (Cardarone, Pacerone) – usually associated with bilateral epididymitis Symptoms Gradual onset of scrotal pain that occasionally radiates to the lower abdomen Dysuria Urethral discharge Abdominal pain Key signs Epididymal tenderness and swelling Scrotal erythema and edema Normal cemasteric reflex Pain relief with testicular elevation (Prehn sign) Diagnostic Tests CBC – increased WBC count with shift to left Gonorrhea and Chlamydia culture Urethral smear (collect before collecting urine) U/A, C&S Ultrasound of scrotum—very important Findings: enlarged, thickened epididymis with increased blood flow on color Doppler Radionuclide scanning Treatment Chlamydia: Floxin, doxycycline, or erythromycin X 10 days Gonorrhea: Rocephin IM X 1 dose or ampicillin po for 10 days Combination therapy: Suprax 400 (or Cipro 500) plus Zithromax 1 gram Bacterial: Cipro, Bactrim DS NOTE: If unsure of etiology, treat with Rocephin and doxycycline while awaiting culture results. Treat partner for STDs Oral NSAID Bed rest for 3-4 days with scrotal elevation on towel until pain is gone Roomy athletic supporter Ice in early phase, heat in later phase Avoid sexual activity and physical strain Complications Testicular atrophy (occurs in 2/3) possibly due to partial vascular thrombosis of the testicular artery Infertility (50% in bilateral epididymitis) Abscess and infarction (5% of cases) Chronic epididymitis P a g e | 27 Testicular Torsion Most common cause of acute scrotum With scrotal pain/masses, this is the first diagnosis to rule out Differentiate from other scrotal problems Testicular torsion presents abruptly with pain Epididymitis incarcerated hernia, and viral orchitis present gradually with scrotal pain Hydrocele, testicular tumor, varicocele, and epididymal cyst are typically painless unless there is a rapid increase in size Clinical findings Initially, the testicle is diffusely tender with hemiscrotal edema and erythema. Eventually, the entire scrotum becomes tender, edematous, and erythematous. The testicle is elevated in the scrotum and may lie in a horizontal position. Elevation of the testicle above the pubic symphysis does not relieve the pain (negative Prehn’s sign); elevation may increase pain Abdominal pain, nausea, and vomiting Absent cremasteric reflex Usually in teenagers and men in their 20s Ultrasound findings: normal-appearing testis with decreased blood flow on color Doppler If found, REFER IMMEDIATELY! This is a surgical emergency. Testicular salvage rate is 90% if detorsion occurs less than 6 hours from the onset of symptoms, but it falls to 50% after 12 hours and to < 10% after 24 hours.
